In honor of The Sporkful’s 15th anniversary, for our Friday Reheats this month we’re pulling especially old episodes out of the darkest recesses of the deep freezer. Today, we’re defrosting our very first Sporkful episode ever, along with our episode on sandwich science with Radiolab co-host Robert Krulwich.

These episodes originally aired on January 15, 2010 and May 17, 2010, and were produced by Dan Pashman and Mark Garrison. The Sporkful team now includes Dan Pashman, Emma Morgenstern, Andres O'Hara, Nora Ritchie, and Jared O'Connell. Publishing by Shantel Holder.

Every other Friday, we reach into our deep freezer and reheat an episode to serve up to you. We're calling these our Reheats. If you have a show you want reheated, send us an email or voice memo at hello@sporkful.com, and include your name, your location, which episode, and why.
